This driver is a simple driver. It provides additional functionality to enable ClearSCADA to interface with specific supported devices using a particular protocol. To interact successfully with such devices, you need to:
- Install and run the driver
- Ensure that the driver is licensed
- Configure the required database items and settings on the driver
- Ensure that the database items (and any database items on which they depend) have valid, saved, configuration and are 'In Service'.
EcoStruxure Web Services (EWS) is a Schneider-defined standard that allows interoperability between Schneider products and devices. ClearSCADA uses this standard to allow transfer of data between the ClearSCADA server and other Schneider applications.
Using the EWS protocol, you can use ClearSCADA’s Simple EcoStruxure Web Services Client Driver to read and/or write to data on EWS servers, including:
- ClearSCADA servers
- Other Schneider Electric servers.
The driver enables ClearSCADA to communicate with servers that comply with EcoStruxure Web Services version 1.1 The driver takes into account any security settings, designed to limit access to configuration properties on many EWS servers.
For information about how to configure EWS specific features and items within the ClearSCADA database,(see Configuring EcoStruxure Web Services Devices in ClearSCADA).
This documentation also explains driver-specific aspects of the driver that may be of interest to system administrators and engineers when investigating unexpected system behavior (relating to the Simple EcoStruxure Web Services Client Driver).
For more information, see EcoStruxure Web Services Specific Status Display Attributes and EcoStruxure Web Services Specific Driver Log File Options.
NOTE: The EcoStruxure Web Services (EWS) Client Driver was previously named the SECWS Client Driver. Any dated references to SECWS or CWS, should be understood as 'EWS'.
NOTE: There are no driver-specific pick actions for database items on this particular driver. However, users with the required privileges can add custom pick actions to a database item by using the User Methods tab on the relevant configuration Form (see Using the User Methods Tab to Define Custom Actions in the ClearSCADA Guide to Core Configuration). See a system administrator for the documentation associated with such custom actions (also known as ‘methods’).
